Definitions

  • the shoe construction of this invention is related to the incorporation of certain materials in layers at the forepart and back part of an insole to substantially improve the cushioning and therefore the comfort of a shoe.
  • Some shoes that have cushioning are suitable for informal wear and it is acceptable that the cushioning be visible such as when provided in the construction of the outsole of the shoe. However, if the shoe is intended for dress or formal wear, visible cushioning is not acceptable and it is important that a dress shoe construction be susceptible to any desired design and appearance.
  • a shoe comprising an upper portion, an insole joined to the upper portion, and an outsole joined to the insole, the insole having a forepart including a layer of foam material the foam layer extending over substantially the entire area directly below the insole forepart of the shoe, the insole having a back part comprising a layer of generally stiff material extending over the heel area of the shoe, the layer of generally stiff material having an opening through the layer of stiff material in the central portion of the heel area, and a foam cushion overlaying the back part of the insole and having a thickened central area projecting into the opening in the back part whereby the strike impact of the heel of a human foot wearing the shoe will be at the thickened central area, and whereby the insole forepart comprises a layer of leather of a thickness of at least 0.99 mm (2.5 ounce) and less than 1.98 mm (5 ounce) with the layer of foam material being located between the leather layer and the outsole, the generally stiff material of the back part of the insole is fibre
  • the present invention thus creates cushioning that is built into both forepart and heel of the shoe and thus avoids the disadvantages of the prior efforts.
  • the shoe of the present invention is described and illustrated in two embodiments. Both embodiments incorporate an insole having a forepart and a back part in which the forepart is made of shoe upper leather and the back part is made of fibreboard having an opening through it.
  • the forepart there is a sheet of foam material, such as microcellular polyurethane, glued to the under surface and extending over the entire area of the forepart that is contacted by the front part of a wearer's foot.
  • foam cushion is connected to and overlies the back part of the insole.
  • the foam cushion has a central projection that projects downwardly through the opening, providing a thicker cushion at the area of strike of the wearer's foot.
  • the combination of the upper leather layer and the microcellular urethane sheet at the forepart provides a very comfortable cushioning effect against downward impact over the entire front portion of the wearer's foot.
  • the microcellular polyurethane overlying the fibreboard provides cushioning for the entire heel area and the thicker central section provided by the projection through the opening in the back part provides maximum cushioning against the impact over the strike area of the heel.
  • the components at the front and at the rear parts of the shoe are connected by bonding a front margin of the back part to a rear margin of the front part.
  • a shoe of welt construction has a tape rib projecting downwardly from the insole defining a cavity, which is where the microcellular polyurethane sheet is located.
  • the sheet of microcellular polyurethane is located over the area within the lasting margin of the upper.
  • a shoe 10 is of welt construction.
  • the shoe 10 incorporates an insole 12 having a forepart 14 and a back part 16.
  • the forepart is made of the kind of leather used for a shoe upper.
  • Shoe upper leather is softer and more flexible and pliable than other leathers. Its thickness typically ranges from about 1.39 mm (3.5 ounce) to about 1.59 mm (4 ounce; an ounce being a unit of thickness for leather equal to 1/64 inch or 0.397 mm).
  • This leather forepart 14 has a lacquered surface so that cement will stick to it but will not penetrate the leather.
  • the back part 16 of the insole 12, unlike the forepart 14, is made of a stiff material, such as fibreboard. Its thickness is about 2.65 mm (five iron).
  • the forepart leather layer 14 has a feathered rear margin 18 and the back part layer 16 has a feathered front margin 20; the margins are cemented together.
  • This shoe being of welt construction, has a continuous tape strip 22, that has flanges 24 and 26 by which the tape is applied and adhered by a standard heat/cement process to the insole 12, locating its downwardly projecting rib 28 spaced inwardly from the outer edge 30 of the insole, as shown in Figure 4.
  • the rib 28 is provided with the usual stiffener 32.
  • the terminal ends 34 and 36 are near the front of the heel area of the insole.
  • a shoe upper 38 (with a liner 40) has a lasting margin 42 cemented in the conventional manner to the outer side of the rib 28 and its flange 24 and to the lower peripheral margin 44 of the back part 16 of the insole 12.
  • the construction and form of the upper and components incorporated in it are conventional.
  • the area within the rib 28 defines a cavity 46, and within this cavity 46, a foam layer 48 is cemented to the forepart 14 of the insole 12.
  • the foam layer 48 is of microcellular polyurethane construction, such as that identified by the trademark PORON and sold by Rogers Corporation of East Woodstock, Connecticut. Preferably the foam layer 48 is about 3 mm (1 ⁇ 8 inch) thick. It is important that the foam layer be compressible and resilient with substantially 100% memory over the life of the shoe.
  • the foam layer 48 has continuous forward and side edges 50 that extend about to the rib 22 and its rear edge 52 is at about the line where the instep begins. Thus the foam layer 48 lies below and can cushion all areas of the foot, forward of the instep, that exert downward pressure on the insole.
  • the foam layer 48 may be provided with a plurality of holes 54 through it spaced over its entire area to influence the compression characteristics of the foam layer 48.
  • the back part 16 of the insole has an oval shaped opening 56 through it located directly below the area where the wearer's heel exerts maximum downward pressure
  • the opening 56 is in the range of 40 mm (1.5 inch) long and 30 mm (9/8 inch) wide.
  • a foam cushion 58 has a tapered forward margin 60 that is cemented to the back part 16 of the insole 12.
  • the foam cushion 58 has a central projection 62 that extends downwardly through the opening 56.
  • the uncompressed thickness of the foam cushion 58 not including the central projection 62 is about 5 mm (3/16 inch) thick and the central portion 62 projects downwardly by a distance of about 3 mm (1 ⁇ 8 inch), making the overall thickness in the area of central projection about 8 mm (5/16 inch) thick.
  • the foam cushion 58 is also preferably of microcellular polyurethane, but is moulded rather than being provided in sheet form as is the case of the foam layer 48.
  • a leather sock liner 64 with a conventional sponge cushion 66 cemented to it has a forward margin 68 where the liner is cemented to the insole 12.
  • the rest of the shoe construction is conventional, including the provision of a welt 68 sewed in place, a shank 70 cemented in place with cork filler alongside the shank 70, an outsole 72, and a heel 74, attached in conventional manners.
  • Figures 6 through 10 illustrate a shoe 80 of cement construction.
  • the shoe 80 has the same insole 12 with its leather forepart 14 and fibreboard back part 16 having the opening 56 through it.
  • an upper 82 with its sock liner 84 has its lasting margin 86 cemented to the outer margin of both the forepart 14 and the back part 16 of the insole 12.
  • the inner edge 88 of the lasting margin 86 defines an area within which a foam layer 48 of the kind previously described lies, cemented to the forepart 14.
  • the same foam cushion 58 as previously described has its forward margin 60 cemented to the back part 16 and its central projection 62 extending downwardly through the opening 56 in the back part 16, all as illustrated in Figures 6 through 8.
  • This shoe also includes the sock liner 64 and its cushion 66 with the sock liner having a forward margin 68 cemented to the back part 16, includes a shank 70 and an outsole 72 and heel 74, all attached in the manner that is conventional for a cement construction shoe.
  • the shoe provides extraordinary comfort to the foot of a wearer.
  • the soft leather of the forepart 14 of the insole 12 cooperates with the foam sheet 48 to cushion the entire front part of the foot.
  • the resilient foam sheet 48 yields and compresses, the insole forepart 14, being pliable, follows the changing contour of the foam sheet while at the same time helping to distribute concentrated loads applied by the foot. Yet although it is rigidly pliable and is soft, the insole forepart 14 is thick enough to endure and last for the life of the shoe.
  • the moulded foam cushion 58 cushions the entire heel of the foot. Moreover, at the strike area where the pressure is greatest, the added thickness of the projection 62 cooperating with the opening 56 that accommodates the projection further cushions that area of concentrated pressure.
  • the sheet and moulding cushion being of microcellular polyurethane, results in cushioning that is yielding and resilient with dependable and complete memory. This foam is fully self restoring and will not lose its resiliency for the life of the shoe.
